Concept explainers
(a)
Interpretation:
The Lewis acid and Lewis base needs to be identified in the reaction of ethylenediamine with
Concept introduction:
The molecules which donate the electrons are known as Lewis bases while the molecules which accept the electrons are known as Lewis acids.
(b)
Interpretation:
The ligands and donor atoms are to be identified.
Concept introduction:
Ligand can be defined as the ion and molecule which have the tendency to donate the electrons to the central atom or ion.
(c)
Interpretation:
The coordination number and geometry of the metal present in the complex are to be determined.
Concept introduction:
The coordination number can be defined as the number of ligands attached to the central atom by coordinate bonds.

- (a) Draw the electronic configuration of [NiCl6]3. (b) Determine whether its paramagnetic or diamagnetic. (c) What is expected to happen to the color if the ligand is replaced by carbonyl?arrow_forwardThe compound Cr(en)2(OH)2Cl has been prepared in several isomeric forms: Isomer A is optically inactive and undergoes no reaction with either AgNO3 or en. Isomer B is optically inactive and reacts with AgNO3 to form a white precipitate, but does not react with en. Isomer C is optically active and reacts both with en and AgNO3.
